Description

Technical Field

[0001] The present invention relates to the technical field of numerically controlled lathes, and in particular to an external measuring and controlling device for improving the precision of machining parts by numerically controlled lathes. Background Art

[0002] In traditional CNC lathes, the precision inspection of machined parts usually relies on manual or simple automated equipment. These methods have some limitations, such as low inspection efficiency and easy inspection errors. Especially when inspecting holes after parts are processed, due to the lack of accurate and automated inspection methods, it is difficult to ensure that the parts processing accuracy meets high quality requirements. In addition, traditional inspection methods often require repeated point selection and manipulation, which not only increases the complexity of operation, but also reduces production efficiency, and human factors are prone to errors.

[0003] When existing CNC lathes use milling cutters to process parts, the milling cutters will wear out due to long-term operation, so errors will occur in the processed parts. The processed parts are currently measured and controlled by PLC industrial controllers to drive external scanning instruments. Impurities may remain on the inner walls of the holes after the parts are processed, so errors will occur when scanning and controlling the parts, thereby reducing production efficiency. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] like Figure 1 - Figure 8As shown, the present invention provides: an external measurement and control device for improving the precision of parts processed by a CNC lathe, comprising a lathe body 10, a conveying member 11 is arranged on one side of the lathe body 10, the conveying member 11 is a conveyor belt in the prior art, and a measurement control unit 12 and a manipulator body 13 used in conjunction with the conveying member 11, the measurement control unit 12 is a visual inspection system in the prior art, so as to detect the size and shape of the processed parts, and unqualified parts can be automatically unloaded through the manipulator body 13, and a detection mechanism 20 capable of detecting holes after the parts are processed is installed on the top of the conveying member 11;

[0042] The detection mechanism 20 includes a fixed frame 21 fixedly installed on the top of the conveying member 11, an electric telescopic rod 22 is fixedly installed on the top of the fixed frame 21, a disc 24 is fixedly installed on the output end of the electric telescopic rod 22, a probe body 25 is arranged at the bottom of the disc 24, and a cleaning component 26 capable of cleaning the holes of the parts and a rotating component 27 used in conjunction with the cleaning component 26 are equipped at the bottom of the disc 24. Electric clamps are arranged on both sides of the fixed frame 21, and the disc 24 is driven to descend by the electric telescopic rod 22. The probe body 25 can be lowered into the hole generated after the parts are processed through the disc 24, and the diameter and shape of the hole are detected by the probe body 25 to judge whether the aperture accuracy of the parts processing is qualified.

[0043] In further detail, the cleaning assembly 26 includes a mounting seat 261 fixedly mounted on the bottom of the disc 24, connecting plates 262 are installed on both sides of the mounting seat 261, a ring 263 is fixedly mounted between the opposite surfaces of the two connecting plates 262, and the ring 263 can be suspended in the air through the two connecting plates 262, and a first gear 264 and a second gear 2613 are arranged on the ring 263, a vertical plate 265 is fixedly mounted on one side of the ring 263, a rack 266 is slidably connected to one side of the vertical plate 265, and a gear 264 is arranged below the second gear 2613. The circular plate 267 is provided with a moving rod 268 which is slidably connected between the circular plate 267 and the second gear 2613. A sponge cover 269 is inserted into one side of the moving rod 268. The inserted sponge cover 269 is convenient for replacement. A first spring 2610 is fixedly installed between the moving rod 268 and the circular plate 267. The first spring 2610 enables the moving rod 268 to drive the sponge cover 269 to reset. At the same time, the sponge cover 269 can contact the hole and wipe it clean, so as to prevent the inner wall of the hole from being produced by the milling cutter, thereby affecting the detection effect.

[0044] A conical seat 2611 is inserted at the bottom of the circular plate 267, and a sleeve 2612 is fixedly installed at one end of the conical seat 2611 extending to the top of the circular plate 267. After the component moves to the bottom of the fixed frame 21, it will be clamped by the electric clamps on both sides. At this time, the probe body 25 descends, and the rack 266 will also contact the top of the component while descending. As the disc 24 descends, the rack 266 is squeezed and raised by the component, and at the same time, the circular plate 267 will also be located inside the hole of the component. At this time, the sponge sleeves 269 on both sides are squeezed by the hole, so that the moving rods 268 on both sides move toward the opposite surface, and the reaction force of the first spring 2610 allows the sponge sleeves 269 to fit with the inner wall of the hole, and the rising rack 266 causes the first gear 264 to rotate through meshing, and the rotation of the first gear 264 causes the second gear 2613 to rotate synchronously, thereby driving the sponge sleeves 269 on both sides to rotate and descend, so as to clean the surface of the hole and prevent measurement errors caused by impurities.

[0045] In further detail, the probe body 25 is located between the mounting seat 261 and the ring 263, the first gear 264 is meshed with the second gear 2613, the rack 266 is meshed with the first gear 264, and a counterweight is provided at the bottom of the rack 266, through which the rack 266 can be lowered by gravity, the inner surface of the sleeve 2612 is provided with a circular sponge, the sleeve 2612 is located directly below the probe body 25, and the opposite surfaces of the fixed frame 21 are provided with electric clamps, and after the conical seat 2611 descends to the bottom, at this time, as the probe body 25 descends, the sleeve 2612 is lifted up by the conical seat 2611, and the probe at the bottom of the probe body 25 is wiped by the sponge on the inner surface of the sleeve 2612, thereby improving the measurement accuracy.

[0046] In further detail, a power source is provided at the bottom of the conveying member 11, the measuring control unit 12 is symmetrically arranged on both sides of the conveying member 11, the manipulator body 13 is arranged at the unloading port of the conveying member 11, and a sensor is provided on the side of the fixed frame 21 close to the measuring control unit 12. When the sensor detects the component, the electric clamps on both sides are driven by the PLC industrial controller to clamp the component, and then the electric telescopic rod 22 on the top is started again to drive the disc 24 to descend.

[0047] Working principle: When in use, the parts are processed by the milling cutter on the lathe body 10. After the processing is completed, the parts are placed on the conveying member 11, and the conveying member 11 is driven by the power source to start conveying the parts. The PLC industrial controller drives the measuring control units 12 set on both sides to detect the size and shape of the parts. When the parts move to the bottom of the fixed frame 21, the sensor on one side sends an electrical signal to the PLC industrial controller. At this time, the PLC industrial controller drives the electric clamps and electric telescopic rods 22 on both sides to operate. The electric clamps first clamp and fix the parts, and then the electric telescopic rod 22 drives the disc 24 to descend, and the disc 24 drives the probe body 25 to descend;

[0048] While descending, the rack 266 will also contact the top of the component. As the disc 24 descends, the rack 266 is squeezed by the component and rises, and at the same time, the circular plate 267 is also located inside the hole of the component. At this time, the sponge sleeves 269 on both sides are squeezed by the hole, so that the moving rods 268 on both sides move toward the opposite surface, and the reaction force of the first spring 2610 allows the sponge sleeves 269 to fit with the inner wall of the hole, and the rising rack 266 causes the first gear 264 to rotate through meshing, and the rotation of the first gear 264 causes the second gear 2613 to rotate synchronously, thereby driving the sponge sleeves 269 on both sides to rotate and descend, so as to clean the surface of the hole and prevent measurement errors caused by impurities;

[0049] After the conical seat 2611 descends to the bottom, as the probe body 25 descends, the sleeve 2612 is lifted up by the conical seat 2611, and the probe at the bottom of the probe body 25 is wiped by the sponge on the inner surface of the sleeve 2612 to improve the measurement accuracy. At this time, the rack 266 rises to the top, so that the sponge sleeves 269 on both sides stop rotating, and then the diameter and shape of the hole are detected by the probe body 25. When errors are detected in the processed holes, the robot body 13 at the discharge port can automatically remove unqualified parts, thereby improving the precision measurement and control of the parts.

[0050] like Figure 5 - Figure 8As shown, the rotating assembly 27 includes a square block 271 symmetrically installed at the bottom of the second gear 2613, a lifting block 272 is inserted at the bottom of the square block 271, a fifth spring 273 is fixedly installed between the lifting block 272 and the square block 271, and a placement frame 274 is fixedly installed at the bottom of the ring 263, and a tilting block 276 and a paddle 277 are symmetrically arranged on the placement frame 274. When the second gear 2613 rotates, the square block 271 at the bottom is also driven to rotate. When the lifting block 272 rotates with the square block 271, the bottom inclined surface of the lifting block 272 will contact the top inclined surface of the tilting block 276. Since there are few contact points between the two inclined surfaces, the friction force generated will be small, and the tilting block 276 will not be driven to move. The lifting block 272 is gradually squeezed by the top inclined surface of the tilting block 276, and after separating from the tilting block 276, the lifting block 272 is reset by the reaction force of the fifth spring 273.

[0051] In further detail, one side of the lifting block 272 close to the tilting block 276 is set as an inclined surface, the top of the tilting block 276 is set as an inclined surface, and one end of the paddle 277 extends to the outside of the placement rack 274, and this end can contact the tilting block 276.

[0052] In further detail, a rubber pad is provided at one end of the paddle 277 close to the moving rod 268, while the other parts of the paddle 277 are still made of hard material, and the other end of the paddle 277 close to the side of the tilting block 276 is set as an inclined surface.

[0053] In further detail, a seventh spring is fixedly connected between the paddle 277 and the placement frame 274 , and the paddle 277 and the moving rod 268 are located correspondingly.

[0054] In further detail, the length of one side of the paddle 277 close to the tilting block 276 is shorter than the tilting block 276, and the paddle 277 can be squeezed by the tilting block 276, and the tilting block 276 is rotatably installed in the rotating groove at the top of the placement frame 274, and a third spring is fixedly connected between the rotating groove and the tilting block 276. When the square block 271 rotates in the opposite direction, the bottom inclined surface of the lifting block 272 will contact the top inclined surface of the tilting block 276. Since the contact points of the two inclined surfaces are small, the friction force generated will be small, and at the same time, the tilting block 276 is pressed by the third spring. The traction of 276 prevents the tilting block 276 from rotating with it. When the lifting block 272 rotates clockwise, the side that is not the inclined surface will contact the tilting block 276, thereby squeezing the tilting block 276, causing the tilting block 276 to start rotating. After rotating to a certain distance, the pulling force of the third spring reaches its peak. At this time, the inclined surface at the bottom of the lifting block 272 will gradually contact the tilting block 276 and cause the tilting block 276 to gradually squeeze and rise, thereby breaking contact with the tilting block 276, and the tilting block 276 is reset by the pulling force of the third spring.

[0055] Working principle: When the second gear 2613 rotates, it will also drive the bottom square block 271 to rotate counterclockwise. When the lifting block 272 follows the rotation of the square block 271, the bottom inclined surface of the lifting block 272 will contact the top inclined surface of the tilting block 276. Since there are few contact points between the two inclined surfaces, the friction force generated will be small, and the tilting block 276 will not be driven to move. The lifting block 272 is gradually squeezed by the top inclined surface of the tilting block 276. After separating from the tilting block 276, the reaction force of the fifth spring 273 causes the lifting block 272 to reset.

[0056] After the hole measurement and control is completed, the disc 24 is driven to rise by the electric telescopic rod 22, thereby driving the probe body 25 to rise. At this time, the rack 266 descends through the counterweight block at the bottom, thereby causing the second gear 2613 to rotate clockwise. At this time, the conical seat 2611 drives the sleeve 2612 to descend through gravity, and the square block 271 follows the second gear 2613 to rotate clockwise at this time. The side that is not the inclined surface will contact the inclined block 276, thereby squeezing the inclined block 276, causing the inclined block 276 to start rotating. While rotating, the inclined block 276 will also squeeze the extended end of the paddle 277, causing the paddle 277 to move in the direction of the moving rod 268. At this time, the rotation The moving moving rod 268 will contact with the extended paddle 277 and squeeze the paddle 277 to deform it, and the vibration generated during the contact will shake off the impurities adhering to the surface of the sponge cover 269, so as to prevent the impurities from adhering to the sponge cover 269 and affecting the next part with inspection. After rotating to a certain distance, the tension of the third spring reaches the peak, and the inclined surface at the bottom of the lifting block 272 will gradually contact with the tilting block 276 and make the tilting block 276 gradually squeeze and rise, and then break away from the tilting block 276, and the tilting block 276 is reset by the tension of the third spring. Since the length of the tilting block 276 is greater than that of the moving rod 268, the moving rod 268 is no longer in contact with the paddle 277.

[0057] As the tilting block 276 rotates, the tilting block 276 will no longer be in contact with the paddle 277, and the paddle 277 will be pulled back to its original position by the seventh spring. The front end of the paddle 277 can recover from the deformation through its own flexible rubber material, and the vibration generated when the continuously extending paddle 277 contacts the moving rod 268 can be used to clean the sponge cover 269.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
